Embodiment 1

[0025] Common 100-denier polyester yarns are used as the linear base material 4, and under the action of the coating transmission mechanism 5 composed of the input device 52 and the output device 51, the common 100-denier polyester yarns are input by the input device 52 at a speed of 1 m / s. The speed is continuously input and output by the output device 51 at an output speed of 1 m / s. During the conveying process, the two ends of the ordinary 100-denier polyester yarn continue to rotate clockwise along its own axis at a rotation speed of 10 rpm. The carbon nanotube viscose nanofiber 3 formed by spraying out the carbon nanotube viscose nanofiber 3 formed by the 5% carbon nanotube and the 95% viscose blend in the electrospinning box 1 through the spinning port 2 is directed toward the Ordinary 100-denier polyester filaments fall, and are wound and coated on ordinary 100-denier polyester filaments with the rotation of ordinary 100-denier polyester filaments. The polyester solution...

Embodiment 2

[0028] Using ordinary 80-count cotton yarn as the linear substrate 4, under the action of the covering transmission mechanism 5 composed of the input device 52 and the output device 51, the ordinary 80-count cotton yarn is continuously Input and output by the output device 51 at an output speed of 500 m / s. During the conveying process, the input end of the ordinary 80-count cotton yarn continues to rotate clockwise along its own axis at a rotation speed of 3000 rpm, and the output end continues to rotate clockwise at a speed of 5000 m / s. The rotation speed of revolution / second rotates clockwise along its own axis, and the nano-silver particles with a mass percentage of 2% and the polylactic acid blend solution with a mass percentage of 98% in the electrospinning box 1 are sprayed out through the spinning port 2 to form The nano-silver polylactic acid nanofiber 3 falls to the ordinary 80-count cotton yarn under the action of an electric field, and is wound and coated on the ordi...

Embodiment 3

[0031] Using flax fiber as the linear substrate 4, under the action of the coating transmission mechanism 5 formed by the input device 52 and the output device 51, the flax fiber is continuously input by the input device 52 at an input speed of 1000 m / s, and is sent to the output device 51 is output at an output speed of 1000 m / s, and continuously rotates counterclockwise along its own axis at a rotation speed of 7000 r / s during the conveying process, and the polyacrylonitrile spinning in the first and second electrospinning boxes 1 The polyacrylonitrile nanofiber 3 formed by the liquid spraying out through the spinning port 2 falls to the flax fiber under the action of the electric field, and is wound and coated on the flax fiber with the rotation of the flax fiber. Continuously transported and rotated under the action of the transmission mechanism 5, the polyacrylonitrile nanofiber 3 continuously covers the flax fiber to form a continuous polyacrylonitrile nanofiber-coated li...

Abstract

The invention relates to nanometer fiber covering linear recombination material that is made up of linear basal material and nanometer fiber covering layer. It conquers the disadvantages of nanometer fiber itself, and has the feature and function of nanometer fiber and keeps all the capability advantages of linear recombination material itself. It could be used in all fields that use linear material.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a linear composite material coated with nanofibers and a preparation method thereof. Background technique [0002] Most of the nanofibers that can be obtained so far are in non-woven form and cannot be woven, so they can only be used in relatively narrow fields, such as filter materials, tissue skeletons, membrane materials and wound dressings. However, judging from the current situation of the use of traditional fibers, only when continuous single nanofibers or uniaxial nanofiber tows are produced, the practical application of nanofibers can be infinitely expanded. [0003] At present, some methods for preparing continuous single nanofibers or uniaxial nanofiber tows have been reported at home and abroad. Chinese patent 200510095384 and patent 200510038571.5 all involve the collection of nanofiber filaments, but the nanofibers and All filament bundles have the defect of insufficient stre...
